This utility function instructs the RM/Panels runtime system to perform all subsequent screen output without color specifications.
RMPANELS.WS contains a parameter that can be set to force monochrome operation (RMP--FORCE-MONO), but this parameter is only checked when a panel library is opened. This utility function allows the application program to change to monochrome operation at any time.
This utility function does not automatically redisplay any information that is on the monitor. After executing this utility function, the application program should redisplay any information it wants to have redisplayed in monochrome.
